I'm a little confused on which 30" Series 380 Channel Balance to use, 2940 or 2950. My window weigHits 27 lb. Please advise.
Thank you for your time.

Paul from SWISCO responded:
If your sash weighs 27 pounds, then I'd go with the 2940 option. This can carry a sash weight of 23 through 28 pounds. The 2850 option carries 28 through 32 pounds, which would be too strong.
